Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention aims to provide a structure for attaching an assembly body capable of accommodating various types of equipment to an object to be attached via an assembly body mounting device, in which the assembly body and the assembly body mounting device can be assembled using only a locking structure without the use of connecting bolts. [Means for solving the problem]

[0006] The invention of claim 1, which solves the above problem, It consists of a plate-shaped mounting body and a mounting fixture for attaching the mounting body to an object to be mounted. The mounting fixture comprises a holding portion for holding the mounting fixture and a fixing portion that is fixed in contact with the outer surface of the object to be mounted extending in at least one direction, The retaining portion extends in a short-angled trough shape from one end to the other, and has an opening that is continuous along the direction of extension. An insertion groove for the assembly is formed therein, which is wide enough to allow a portion of the peripheral edge of the assembly to be inserted inward from the opening. At least one of the opposing inner surfaces of the insertion groove for the assembly is provided with a locking portion that is fitted in a locked state into a recess formed on at least one of the front and back surfaces of the assembly, to which a portion of the peripheral edge is positioned in the insertion groove for the assembly. The locking portion is fitted into the recess in a locked state, thereby preventing both relative movement of the mounting body and the mounting body attachment in the direction of extension of the holding portion, and relative movement of the mounting body in the direction of disengaging from the opening of the holding portion.

[0007] According to the invention of claim 1, when a portion of the peripheral edge of an assembly, which is arranged parallel to the object to be attached, is inserted into the assembly insertion groove through the opening of the holding portion of the assembly mounting fixture, a locking portion formed on at least one of the opposing inner surfaces of the assembly insertion groove engages with a recess formed on at least one of the front and back surfaces of the assembly, thereby easily assembling and holding the peripheral edge of the assembly to the holding portion of the assembly mounting fixture. In this way, since the locking portion is engaged with the recess of the assembly, the assembly can be assembled and held to the holding portion of the assembly mounting fixture using only the locking structure without using connecting bolts, so that the assembly and holding work between the assembly and the assembly mounting fixture can be performed with a single touch, and relative movement of the assembly and the assembly mounting fixture in the direction extending the holding portion, and relative movement of the assembly in the direction of coming out of the opening of the holding portion are both prevented.

[0009] According to the invention of claim 2, the recesses on the front and back of the mounting body are engaged with the front and back locking portions formed on the holding portion of the mounting body attachment, respectively. As a result, the mounting body is engaged with the front and back locking portions along the thickness direction on both its front and back surfaces, and is held in the holding portion with good holding balance along the thickness direction of the mounting body. The engagement between the recesses on the front of the mounting body and the front locking portions of the holding portion prevents relative movement of the mounting body and the holding portion of the mounting body attachment in the extending direction.

[0010] The invention of claim 3 is, in the invention of claim 2, The aforementioned assembly comprises a main body having a plurality of pre-drilled holes for fixing various devices arranged on the front side, and an annular rib extending along the periphery of the main body and toward the back side of the main body, The front locking portion is characterized by being fitted into the pilot hole of the assembly, thereby preventing relative movement of the holding portion in the extending direction, and the back locking portion is characterized by being fitted into the back side of the annular rib of the assembly, thereby preventing relative movement of the assembly in the withdrawal direction.

[0011] According to the invention of claim 3, the mounting body comprises a main body portion having a plurality of pilot holes formed therein, and an annular rib extending along the periphery of the main body portion and toward the rear side of the main body portion, wherein the locking portions on the front and rear sides are structured to lock into the pilot holes, and the mounting body can be held by the holding portion of the mounting body attachment by utilizing the division groove portion and the annular rib which are functionally inherent to the mounting body, without providing a locking recess in the mounting body solely for the purpose of realizing the locking structure.

[0012] The invention of claim 4 is, in the invention of claim 3, The holding portion of the mounting fixture functions as a parallel holding portion that, while fixed to the object to be mounted by the fixing portion, holds the surface direction of the mounting fixture parallel to the outer surface of the object to be mounted. The mounting fixture further includes an orthogonal holding part that, while fixed to the object to be mounted by the fixing part, maintains a state in which the surface direction of the mounting fixture is orthogonal to the outer surface of the object to be mounted. The orthogonal holding portion comprises a rib insertion groove into which a portion of the annular rib in the circumferential direction can be inserted, and an assembly screw insertion portion into which an assembly screw that has passed through the main body of the assembly is screwed in with a portion of the annular rib in the circumferential direction inserted into the rib insertion groove, The present invention is characterized in that a portion of the annular rib is inserted into the rib insertion groove of the orthogonal holding portion of the mounting fixture, and the assembly screw that penetrates the main body of the mounting fixture is screwed into the assembly screw screw insertion portion of the orthogonal holding portion, thereby aligning the surface direction of the mounting fixture to be perpendicular to the outer surface of the object to be mounted.

[0013] According to the invention of claim 4, in addition to the configuration in which a part of the peripheral edge of the mounting body is inserted into a mounting body insertion groove formed in the holding part of the mounting body fixture to position the mounting body parallel to the object to be mounted, it is also possible to hold the mounting body in a configuration perpendicular to the object to be mounted by providing a rib insertion groove into which a part of the peripheral edge of the annular rib can be inserted, and an assembly screw screw insertion part into which an assembly screw that penetrates the main body of the mounting body is screwed in with a part of the peripheral edge of the annular rib inserted into the rib insertion groove, thereby enabling the mounting body to be held perpendicular to the object to be mounted.

[0014] The invention of claim 5 is the invention described in any one of claims 1 to 4, The aforementioned mounting consists of at least two types with different thicknesses in the front and back directions. The holding portion of the mounting fixture is characterized by comprising a narrow holding portion and a wide holding portion corresponding to the plate thickness of the two types of mounting fixtures.

[0015] According to the invention of claim 5, two types of mounting fixtures with different thicknesses in the front-back direction, i.e., plate thickness, can be positioned and held parallel to the object to be mounted, using the same mounting fixture.

[0016] The invention of claim 6 is the invention described in any one of claims 1 to 3, The object to be attached consists of a rod-shaped body extending in the axial direction, The fixing portion of the mounting fixture is provided with an elastic piece integrally attached to the holding portion such that a receiving opening is formed to allow the rod-shaped body, which is arranged with its axial direction perpendicular to the extending direction of the holding portion, to be received. With a pair of mounting fixtures attached to opposing parallel sides on the periphery of the aforementioned mounting body, such that the receiving openings face in opposite directions, With the back surface of the disposed body facing the rod-shaped body, the surface direction of the disposed body is arranged along the axial direction of the rod-shaped body, and the disposed body is rotated about its central portion as the rotation center, so that the rod-shaped body is relatively inserted through the receiving openings of the elastic pieces of the pair of disposed body fixtures and is clamped by the elastic pieces, whereby each fixing portion of the disposed body fixture is fixed at two positions displaced along the axial direction of the rod-shaped body.

[0017] According to the invention of claim 6, with the pair of disposed body fixtures attached to the parallel side portions facing each other at the peripheral portion of the disposed body such that the receiving openings face in opposite directions, the back surface of the disposed body is directed toward the rod-shaped body, and the surface direction thereof is arranged along the axial direction of the rod-shaped body. The disposed body is rotated about its central portion as the rotation center, and the rod-shaped body is relatively inserted through the receiving openings of the elastic pieces of the pair of disposed body fixtures. As a result, each fixing portion of the disposed body fixture is fixed at two positions displaced along the axial direction of the rod-shaped body by being clamped by the elastic pieces, and the disposed body can be fixedly arranged parallel to the rod-shaped body by using the pair of disposed body fixtures.

[0018] The invention of claim 7 is A disposed body fixture for attaching a plate-shaped disposed body to an object to be attached, comprising a holding portion for holding the disposed body, and a fixing portion fixed in contact with at least one outer surface of the object to be attached extending in one direction, The holding portion extends in a short-angle gutter shape from one end to the other end and has continuous openings along the extending direction. A disposed body insertion and arrangement groove is formed with a width that allows a part of the peripheral portion of the disposed body to be arranged inside from the opening. On the opposing inner surfaces of the disposed body insertion and arrangement groove, locking portions are provided that are respectively fitted in a locked state with the recesses formed on both the front and back surfaces of the disposed body. The engaging portion is composed of a front-side engaging portion and a back-side engaging portion that are respectively engaged in a fitting state with the front-side and back-side recesses formed on the front and back of the disposed body. The engaging structures on the front and back of the disposed body cooperate to prevent both relative movement of the disposed body and the disposed body fixture in the extending direction of the holding portion, and relative movement of the disposed body in the direction of exiting from the opening of the disposed body fixture.

[0019] The invention according to claim 7 is an expression obtained by grasping the invention according to claim 2 as a "disposed body fixture", and the substantial operational effects are the same as those of the invention according to claim 2.

[0020] The invention according to claim 8 is based on the invention according to claim 7, The fixing portion has a clamping portion whose tip side extends in a direction orthogonal to the one direction, can receive a rod-shaped body that constitutes the object to be attached and extends with the one direction as the axial direction, and can clamp the received rod-shaped body.

[0021] According to the invention of claim 8, a clamping portion whose tip end portion extends in a direction facing a direction orthogonal to the one direction is provided on the fixing portion that constitutes the disposed body fixture, and by the clamping portion receiving and clamping the rod-shaped body, the disposed body fixture is fixed to the rod-shaped body.

[0022] The invention according to claim 9 is based on the invention according to claim 7 or 8, The holding portion is composed of a narrow-width holding portion and a wide-width holding portion in which the openings face in opposite directions and the width of the disposed body insertion and arrangement groove is relatively different.

[0023] According to the invention of claim 9, two types of disposed bodies with different plate thicknesses can be held by the same disposed body fixture.

Effects of the Invention

[0024] According to the present invention, when a portion of the peripheral edge of an assembly, which is positioned parallel to the object to be attached, is inserted into the assembly insertion groove through the opening of the holding portion of the assembly mounting fixture, a locking portion formed on at least one of the opposing inner surfaces of the assembly insertion groove engages with a recess formed on at least one of the front and back surfaces of the assembly, thereby easily assembling and holding the peripheral edge of the assembly to the holding portion of the assembly mounting fixture. In this way, since the locking portion engages with the recess of the assembly, the assembly can be assembled and held to the holding portion of the assembly mounting fixture using only the locking structure, without using connecting bolts. This allows the assembly and holding of the assembly and the assembly mounting fixture to be performed with a single touch, and prevents both relative movement of the assembly and the assembly mounting fixture in the direction of extension of the holding portion, and relative movement of the assembly in the direction of coming out of the opening of the holding portion.

[0025] Furthermore, as in the invention of claim 2, by configuring the locking portion with a front locking portion and a back locking portion that are fitted and locked into recesses formed on the front and back of the front and back of the mounting body, respectively, the mounting body is held in the holding portion of the mounting body mounting fixture with good holding balance along the thickness direction of the mounting body. Also, as in the invention of claim 5, by configuring the holding portion of the mounting body mounting fixture with a narrow holding portion and a wide holding portion corresponding to the widths of two types of mounting bodies with different thicknesses, the two types of mounting bodies can be held in parallel to the object to be mounted using the same mounting body mounting fixture.

[Figure 20] This is a perspective view showing the relationship between the multiple protrusions 9a and 9b of the mounting bracket A and the shape of the back surface of the main body 21 of the mounting unit D1. [Modes for carrying out the invention]

[0027] The present invention will be described in more detail below with reference to the best embodiment. First, the mounting bracket A and the mounting brackets D1 and D2, each having two different plate-shaped mounting elements D1 and D2 having different plate thicknesses, will be described. Then, a method for attaching the mounting bracket A to the bolt shaft B in two different forms will be described. Both the mounting bracket A and the mounting brackets D1 and D2 are injection-molded resin products.

[0028] As shown in FIGS. 1 to 5, the fixture A for a disposed body has first and second holding portions H1 and H2 in the shape of short-angle troughs for holding two types of the disposed bodies D1 and D2 having different plate thicknesses. By arranging them back to back, the bottom plate portion 1 is shared, and the groove openings 2a and 2b (see FIGS. 1(a) and 3(b)) face opposite sides and are integrated. On the outer surface of one side plate portion 3a1, 3a2 of the integrated holding portions H1 and H2, a fixing portion F for fixing the entire fixture A for the disposed body is integrally formed along a direction orthogonal to the groove formation direction P of the holding portions H1 and H2 along the bolt axis B. That is, in the first and second holding portions H1 and H2 in the shape of short-angle troughs, first and second disposed body insertion grooves 4a and 4b for inserting and arranging a part of the outer peripheral portions of the disposed bodies D1 and D2 arranged parallel to the bolt axis B are formed with their groove openings 2a and 2b facing opposite sides, and both ends of the groove formation direction P of the disposed body insertion grooves 4a and 4b are open. The groove widths of the disposed body insertion grooves 4a and 4b are W1 and W2 (W1 < W2) (see FIG. 3(a)), respectively. The disposed body insertion groove 4b of the second holding portion H2 for holding the disposed body D2 with a large plate thickness is formed by the side plate portions 3a2 and 3b2 forming the short-angle trough shape. However, the disposed body insertion groove 4a of the first holding portion H1 for holding the disposed body D1 with a small plate thickness is formed by the other side plate portion 3b1 and a thick plate-shaped inner side plate portion 5 integrally provided along the groove formation direction P inside the disposed body insertion groove 4a close to the side of the side plate portion 3a1 in the groove width direction.

[0029] Here, as shown in Figures 6 to 8 and 14 to 16, each of the mounting bodies D1 and D2 with different plate thicknesses T1 and T2 has an annular rib 22 (22') integrally formed on the periphery of the square-shaped or rectangular main body 21, facing the back side. On the front side of the main body 21 (21'), multiple first and second grooves 23 (23') and 24 (24') are formed at equal intervals, perpendicular to each other. In the square-shaped portion surrounded by each groove 23 (23') and 24 (24'), countless screw holes 25 are formed at small intervals in a direction parallel to the first and second grooves 23 (23') and 24 (24') into which screws for fixing fixtures disposed on the surface of each mounting body D1 and D2 are screwed. Therefore, the fixing points for various fixtures placed on the surface of the mounting body D1 are located at the same position as or close to any of the countless screw holes 25, making it possible to fix fixtures of various shapes without having to separately provide specific fixing points corresponding to the shape of the fixtures. Each mounting body D1, D2 is attached to the bolt shaft B using the mounting body mounting fixture A, parallel or perpendicular to its axis. In addition, screw insertion holes 26 (26') are formed at each corner of the main body portion 21 (21') of each mounting body D1, D2 for inserting screws (not shown) to directly attach each mounting body D1, D2 to a vertical wall surface, horizontal ceiling surface, etc.

[0030] On the inner surface of the inner side plate portion 5 facing the other side plate portion 3b1, a pair of rear-side locking portions 6a1 are formed at predetermined intervals along the groove formation direction P between them and the bottom plate portion 1, with a spacing corresponding to the thickness of the annular rib 22 of the thin-plate-thick-plate-body-D1. As shown in Figure 11, by relatively rotating the entire assembly mounting fixture A, which is positioned at an angle to the assembly D1 in a side view, a part of the annular rib 22 of the thin-plate-thick-plate-body-D1 is inserted and locked in a fitted state between the bottom plate portion 1 and the pair of rear-side locking portions 6a1. Furthermore, on the inner surface of the other side plate portion 3b1 in the first arrangement insertion groove 4a, a single front-side locking portion 6a2 is formed along the groove formation direction P at an intermediate position between the pair of back-side locking portions 6a1. This locking portion engages the front-side projection 27 (see Figure 11), which is the front-side projection of the annular rib 22 on the main body portion 21, when inserted into the central first groove portion 23 of a plurality of first groove portions 23 (three in this embodiment). The back-side locking portion 6a1 and the front-side locking portion 6a2 prevent relative movement between the arrangement body D1 and the arrangement body mounting fixture A along the groove formation direction P, and prevent the arrangement body D1 from coming out of the groove opening 2a of the first holding portion H1 of the arrangement body mounting fixture A. On the inner surfaces of each side plate portion 3a2, 3b2 that form the second arrangement insertion groove 4b of the second holding portion H2, a pair of back-side locking portions 6b1 and a single front-side locking portion 6b2 are formed in the same arrangement as in the first holding portion H1.

[0031] The pair of rear-side locking portions 6a1 (6b1) and the single front-side locking portion 6a2 (6b2) are used when the mounting bodies D1 and D2 are mounted parallel to the bolt shaft B. However, by designing the shape of the thick plate-like internal side plate portion 5 formed along the groove formation direction P in the middle of the groove width direction of the first holding portion H1, and by designing the position of the internal side plate portion 5 along the groove width direction, the mounting body D1 can be mounted perpendicular to the axis of the bolt shaft B using the mounting body mounting device A. Specifically, a rib insertion groove 7 is formed between the thick plate-like internal side plate portion 5 and the side plate portion 3a1 of the first holding portion H1, into which a part of the annular rib 22 on the back side of the mounting body D1 can be inserted. In addition, a plurality of contact protrusions 8 are provided at predetermined intervals and protruding upward along the groove formation direction P on the portion of the upper end surface of the internal side plate portion 5 facing the rib insertion groove 7 along the plate thickness direction. Multiple contact protrusions 8 (four in this embodiment) are formed at predetermined intervals to avoid interference with multiple back-side protrusions 9a, 9b formed close to the annular rib 22 on the back surface of the main body portion 21 of the mounting body D1, as shown in Figures 8(c) and 19(b). The mounting body D1, which is horizontally positioned perpendicular to the bolt axis B, is supported by the multiple contact protrusions 8 and the upper end surface of the side plate portion 3b1, and is positioned perpendicular to the bolt axis b, so these parts are referred to as the perpendicular-positioned portion K. In the central part of the internal side plate portion 5 along the groove formation direction P, an assembly screw insertion portion 11 is formed for screwing in assembly screws 61 to assemble and fix the mounting body D1, which is horizontally positioned with a part of its entirety supported by the perpendicular-positioned portion K, to the first holding portion H1 of the mounting body attachment A using a screw fixing structure. The assembly screw insertion portion 11 is composed of a screw pilot hole groove 12 that is narrower than the outer diameter of the assembly screw 61, and the screw pilot hole groove 12 is formed through the center of the groove formation direction P of the internal side plate portion 5, opening to the side of the first arrangement member insertion groove 4a.

[0032] As shown in Figure 19, the height of the side plate portion 3a1, which forms the rib insertion groove 7 with the internal side plate portion 5, from the bottom plate portion 1 is higher than that of the other side plate portion 3b2 in order to allow contact with the entire thickness direction of the assembly body D1. In the center of the groove formation direction P of the side plate portion 3a1, there is a proper placement confirmation recess 13 which, when the assembly body mounting fixture A is attached to the outer circumference of each assembly body D1, D2, can be confirmed in plan view to be positioned on the extension line of the central first groove portion 23(23') of the multiple first groove portions 23(23') formed on the surface of the main body portion 21(21') of each assembly body D1, D2.

[0033] Furthermore, each side plate portion 3a1, 3a2 of the mounting fixture A is formed as a continuous single plate, and the fixing portion F is integrally formed on the outer surface of each side plate portion 3a1, 3a2. The fixing portion F consists of a partial planar female thread portion 14 formed along the height direction of the mounting fixture A to partially screw in the bolt shaft B at the central part along the groove formation direction P of each side plate portion 3a1, 3b2, and at a portion slightly below the central part of the total height when the side plate portions 3a1, 3a2 are combined, and an elastic piece 15 which is integrally formed on each side plate portion 3a1, 3b2 so as to cover the entire partial planar female thread portion 14 and is substantially L-shaped in plan view. The elastic piece 15 consists of an upright plate portion 15a formed perpendicular to each of the side plate portions 3a1 and 3a2, and a bolt shaft elastic contact plate portion 15b arranged perpendicular to the upright plate portion 15a and parallel to each of the side plate portions 3a1 and 3b1. The space formed by the bolt shaft elastic contact plate portion 15b, the upright plate portion 15a, and each of the side plate portions 3a1 and 3b1 is a bolt shaft arrangement space 16 in which a portion of the bolt shaft B along the axial direction is arranged. The partial planar female thread portion 14 has a configuration in which a plurality of linear thread grooves corresponding to the threads of the bolt shaft B are formed vertically in the central part along the groove formation direction P on the outer surface of the side plate portions 3a1 and 3b2 of the mounting fixture A, with the same pitch as the thread pitch of the bolt shaft B. With the partial flat female thread portion 14 partially screwed onto the bolt shaft B, the position of the bolt shaft B along the groove formation direction P is the same as the position of the proper position confirmation recess 13.

[0034] With the above structure, as described later, one of the pair of mounting fixtures A can be inverted vertically and attached to the center of the opposing sides of the square-shaped mounting fixture D1 and the rectangular mounting fixture D2, allowing the bolt shaft B to be partially screwed into each of the partial planar female threaded portions 14 of each mounting fixture A. The opening between the tip (free end) of the bolt shaft elastic contact plate portion 15b and the respective side plate portions 3a1, 3b1 serves as a bolt bearing insertion opening 19 for receiving the bolt shaft B into the bolt shaft arrangement space 16. At the center of the height direction of the tip of the bolt shaft elastic contact plate portion 15b, a rotation restricting screw hooking plate portion 17 is integrally provided, protruding in the groove forming direction P, for hooking the head 62a of a rotation restricting screw 62 that restricts the rotation of the mounting fixture A relative to the bolt shaft B when a portion of the axial direction of the bolt shaft B is inserted into the bolt shaft arrangement space 16. The rotation-restricting screw 62, inserted into the screw insertion groove 17a formed in the downward-opening part of the rotation-restricting screw hook plate 17, is screwed into the inner side plate 5 through the screw insertion groove 18 formed in the side plate 3a1, which is open at the top. The bolt shaft elastic contact plate 15b elastically contacts the part of the bolt shaft B that is opposite to the screwed portion to the partial flat female thread portion 14, thereby restricting the rotation of the mounting fixture A relative to the bolt shaft B.

[0035] Next, with reference to Figures 9 to 13, a case will be described in which an assembly D1 is attached to a vertically positioned bolt shaft B using a pair of assembly mounting fixtures A, parallel to the axis of the bolt shaft B. As shown in Figure 9, one of the pair of assembly mounting fixtures A is inverted vertically so that the first assembly insertion grooves 4a face each other, and the elastic piece 15 is positioned on the back side. In this state, as shown in Figure 11, when the mounting fixture A is rotated from the inclined position to the normal position, with the opposing portion of the annular rib 22 of the mounting fixture D1 partially inserted into the first mounting fixture insertion groove 4a of each mounting fixture A in an inclined position in a side view, the annular rib 22 on the back side of the mounting fixture D1 is fitted and inserted between the bottom plate portion 1 and a pair of back side locking portions 6a1 and locked in place, and on the front side, the front side locking portion 6a2 is inserted into the central first groove portion 23 of the three first groove portions 23, thereby locking with the front side projection 27 located where the annular rib 22 extends to the front side. As a result, as shown in Figure 11, a pair of mounting fixtures A, arranged upside down, are attached to the center of each of the parallel sides of the mounting fixture D1. The front locking portion 6a2 of the mounting bracket A is inserted into the central first groove 23 of the three first grooves 23 of the mounting body D1, so that the mounting bracket A is inevitably attached to the center of each side of the mounting body D1. In this way, the mounting body D1 is attached to the mounting bracket A only by the locking structure on the front and back of the mounting body D1, so that the attachment work (assembly work) of the mounting bracket A to the mounting body D1 can be performed quickly compared to the conventional structure that uses connecting bolts. The pair of rear-side locking portions 6a1 of the mounting bracket A and the annular rib 22 of the mounting bracket D1 prevent the mounting bracket D1 from coming out of the mounting bracket A, and the single front-side locking portion 6a2 of the mounting bracket A and the front-side projection 27 of the mounting bracket D1 restrict the relative lateral movement between the mounting bracket A and the mounting bracket D1.

[0036] Thus, in order to attach the mounting bracket A to the mounting body D1, the annular rib 22 on the back side and the first groove 23 and projection 27 on the front side, which are functionally indispensable to the mounting body D1, are selected as the mating parts (receiving parts) for the back side locking part 6a1 and the front side locking part 6a2 of the mounting bracket A. In other words, since a functionally indispensable part of the mounting body D1 is used as the mating part (receiving part) of the locking structure, the mounting bracket A can be attached to the mounting body D1 with a single touch using only the locking structure, without having to separately form a part on the mounting body D1 solely for the purpose of locking the mounting bracket A. As a result, it is naturally no longer necessary to use connecting screws (connecting bolts) to attach the mounting bracket A to the mounting body D1, as in conventional structures.

[0037] Next, as shown in Figure 12(a), with the bolt shaft B perpendicular to the back surface of the mounting body D1 facing each other, and with the mounting body D1 inclined relative to the bolt shaft B such that the diagonal direction of the mounting body D1 and the axis of the bolt shaft B substantially coincide, when the mounting body D1 is rotated to the right by a predetermined angle when viewed from the back, the bolt shaft B is relatively received into the bolt shaft arrangement space 16 from the bolt bearing insertion opening 19 of each mounting body A, and the respective partial planar female threaded portions 14 of each mounting body A and two portions of the bolt shaft B at predetermined intervals are partially screwed together, and the bolt shaft elastic contact plate portion 15b of the elastic piece 15 elastically contacts the portion of the bolt shaft B opposite to the partially screwed portion, and the elastic piece 15 and the side plate portion 3a1 of the mounting body A, As the bolt shaft B is sandwiched between 3a2, as shown in Figure 12(b), the mounting fixture A, i.e., the mounting body D1, does not move relative to the axial direction of the bolt shaft B, and the mounting body D1 is attached to the bolt shaft B via the pair of mounting fixtures A, perpendicular to the axis of the bolt shaft B. Finally, when the rotation-restricting screw 62 [see Figure 13(c)] inserted from the screw insertion groove 17a of the rotation-restricting screw hooking plate portion 17 is screwed into the bottom plate portion 1 through the screw insertion groove 18 of the side plate portion 3a1, the elastic contact force of the bolt shaft elastic contact plate portion 15b of the elastic piece 15 with respect to the bolt shaft B increases, and as shown in Figures 13(a) and (b), the rotation of the pair of mounting fixtures A with respect to the bolt shaft B, i.e., the rotation of the mounting body D1 with respect to the bolt shaft B is restricted, and the mounting body D1 is positioned parallel to the bolt shaft B, facing the predetermined direction. Therefore, the first mounting groove 4a of the mounting fixture A, into which the peripheral portion of the mounting body D1 is inserted and positioned, allowing the mounting body D1 to be positioned parallel to the bolt axis B, functions as the parallel positioning portion as defined in claim 3. In Figure 12 and the later Figures 15 and 16, the mounting bodies D1 and D2 are shown in a simplified manner without showing their screw pilot holes 25 and 25', and in Figure 13(c), 63 indicates the fixtures positioned on the surface of the mounting body D1.

[0038] Next, with reference to Figures 14 to 16, a case in which the mounting body D2 is attached to the bolt shaft B using a pair of mounting fixtures A will be described. The mounting body D2 is rectangular in shape and is larger in size than the square mounting body D1, with both its length and width being longer than the length of one side of the mounting body D1, and its plate thickness T2 is greater than the plate thickness T1 of the mounting body D1. The structure itself, in which annular ribs 22' are provided on the periphery of the plate-shaped main body portion 21' toward the back side, is the same as that of the mounting body D1. On the surface of the main body portion 21', a plurality (7) of first grooves 23' are formed at equal intervals in the short direction, and a plurality (4) of second grooves 24' are formed at equal intervals in the longitudinal direction, and countless screw pilot holes 25 are formed in the numerous rectangular portions surrounded by the first and second grooves 23', 24'.

[0039] Furthermore, in order to attach the mounting body D2 to the bolt shaft B via a pair of mounting fixtures A, as shown in Figure 15, the only difference is that the plate thickness T2 of the mounting body D2 is greater than the plate thickness T1 of the mounting body D1, and therefore the second mounting body insertion groove 4b of the mounting fixture A corresponding to the plate thickness T2 is used. Note that in Figure 15, the main body portion 21' of the mounting body D2 is shown in a simplified manner. That is, in exactly the same manner as in the case of assembly D1, with each assembly mounting fitting A positioned at an angle in a side view at the center of each of the opposing long sides of assembly D2, and with a portion of the peripheral edge of assembly D2 partially inserted into the second assembly insertion groove 4b, each assembly mounting fitting A is rotated in a predetermined direction so that its bottom plate portion 1 comes into contact with the planar outer surface of the annular rib 22' of assembly D2, and a portion of the peripheral edge of assembly D2 is inserted into the second assembly insertion groove 4b of each assembly mounting fitting A, and the second assembly insertion groove 4b functions as a parallel arrangement portion as defined in claim 3, which enables the assembly D2 to be arranged parallel to the bolt axis B. As a result, on the back side, the tip of the annular rib 22' is inserted and locked in a fitted state between the pair of back locking parts 6b1 of the mounting fixture A and the bottom plate 1, and on the front side, the pair of front locking parts 6b2 of the mounting fixture A are inserted and locked into the central first groove 23' of the multiple first grooves 23', thereby restricting the lateral relative movement of the mounting fixture A of the mounting fixture A and preventing the mounting fixture D2 from coming out.

[0040] Next, in the same manner as with the assembly D1, the back surface of the assembly D2 to which the pair of assembly mounting fixtures A are attached faces the bolt shaft B, and in a configuration where the diagonal direction of the assembly D2 is substantially aligned with the axis of the bolt shaft B, the assembly D2 is rotated in a predetermined direction to insert two locations at a predetermined interval along the axial direction of the bolt shaft B into the bolt shaft arrangement space 16 of each assembly mounting fixture A. As shown in Figure 16, with the long side of the assembly D2 perpendicular to the bolt shaft B, the assembly D2 is positioned parallel to the bolt shaft B, and the assembly D2 is positioned parallel to the bolt shaft B, which is positioned perpendicular to the bolt shaft B.

[0041] Next, referring to Figures 17 to 20, we will explain the case in which the mounting body D1 is horizontally attached to the vertically positioned bolt shaft B. When the surface of the mounting body D1 is positioned upwards, and the central part of the annular rib 22 of the mounting body D1 is inserted into the rib insertion groove 7 of the mounting body fitting A, and a part of the peripheral edge of the main body 21 of the mounting body D1 is positioned on the orthogonal arrangement portion K of the mounting body fitting A, as shown in Figure 19, a plurality of contact protrusions 8, which are positioned adjacent to the rib insertion groove 7 and abut the back surface of the main body 21 of the mounting body D1, are positioned inside the annular rib 22 of the mounting body D1 along the direction of arrow Q, which is the lateral direction of the mounting body D1, and are positioned between each protrusion 9a, 9b along the direction of arrow R, which is perpendicular to arrow Q, in order to avoid interference, a part of the back surface of the main body 21 of the mounting body D1 is placed on the orthogonal arrangement portion K of the mounting body fitting A, and the mounting body fitting A is horizontally attached to the peripheral edge of one side of the mounting body D1. In the orthogonal arrangement section K of the mounting bracket A, as shown in Figure 19(a), the projection 10 protruding from the back surface of the first groove 23 in the main body 21 of the mounting body D1 abuts against the upper end surface of the other side plate 3b1. In order to position the mounting bracket A in the center of the peripheral edge of one side of the mounting body D1, the alignment of the proper placement confirmation recess 13 of the mounting bracket A and the central first groove 23 among the multiple first grooves 23 of the mounting body D1 is confirmed in a plan view, and the above attachment work is performed. Finally, as shown in Figures 18 and 19, when the assembly screw 61 is screwed into the screw pilot hole groove 12 that constitutes the assembly screw screw insertion section 11 directly below the central first groove 23 of the mounting body D1, the mounting bracket A is integrally assembled to the mounting body D1 via the assembly screw 61.

[0042] With the mounting bracket A horizontally attached to the peripheral edge of one side of the mounting body D1, when the mounting bracket A is fixed to the bolt shaft B via the elastic piece 15, the mounting body D1 is positioned perpendicular to the vertically positioned bolt shaft B, i.e., horizontally. In this way, even when the mounting body D1 is positioned horizontally, the mounting bracket A is attached to the mounting body D1 using the annular rib 22 and main body portion 21, which are functionally indispensable to the mounting body D1, in the same manner as when the mounting body D1 is positioned vertically.

[0043] In the above embodiment, the rear locking parts 6a1, 6b1 and the front locking parts 6a2, 6b2 prevent the removal of the mounting parts D1 and D2 from the mounting fixture A, and also prevent relative movement of the mounting parts. However, it is also possible to create a structure that prevents both using only the rear locking parts or only the front locking parts.

[0044] As described above, when a mounting fixture A is used to horizontally position a mounting body D1 with respect to a vertically positioned bolt shaft B, it is possible not only to attach (fix) the fixtures to the mounting surface on the upper surface of the mounting body D1, but also to position the mounting surface of the horizontally positioned mounting body D1 facing downwards and attach the fixtures to the mounting surface on the lower surface of the mounting body D1.

[0045] In the above-described arrangement examples of each of the mounting units D1 and D2, they are all positioned parallel or perpendicular to the bolt axis B using a mounting unit A equipped with an elastic piece 15. However, it is also possible to position each of the mounting units D1 and D2 perpendicular to the wall surface by extending the side plate portions 3a1 and 3a2 of the mounting unit A in a direction perpendicular to the bottom plate portion 1, omitting the elastic piece 15, and fixing the extended portions of the side plate portions 3a1 and 3a2 to the wall surface of the building using screws or similar fasteners.
